The phone is coming in three colours (gold, silver and space grey) and in three capacities (16GB, 32GB and 64GB).

The outright prices for these three phones will be $869, $999 and $1,129 respectively. Apple has confirmed that Telstra, Optus, Vodafone, Virgin Mobile and "select Apple Authorised Resellers" will sell the phone from Friday September 20.

Confusingly, Apple has five different variants of the iPhone 5S launching around the world to support different network standards.

At this stage it's not clear which versions will be launching in Australia, but looking at the phone's tech specs page, it's interesting to note that the A1530 version supports both FDD-LTE and TD-LTE technologies.

That means that Optus may get a version of the iPhone 5S that supports its TD-LTE network in Canberra.

It also means that we can expect different variants of the handset for different carriers, which should make grey importing the phone slightly more confusing.

Other iterations of the handset all support the LTE bands currently used by Telstra and Vodafone, meaning there shouldn't be any issues connecting in the short term.

iPhone 5C

Just like the premium iPhone 5S, the iPhone 5C will be launching in Australia on September 20.
